Secrets of the Swamp': Why firefighter Brandy Hall's disappearance puzzles investigators 20 years later

Two decades after Brandy Hall disappeared, investigators say evidence still points to foul play. The 32-year-old Florida volunteer firefighter was last seen leaving her shift around 10:50 p.m. on Aug. 17, 2006—the day before she was expected to testify in her husband Jeff Hall’s sentencing hearing. She never appeared. A fisherman later found her fire gear floating in a pond, and police divers recovered her truck about two miles from the Malabar Volunteer Fire Department; officials reported a large amount of blood on the driver’s side. Prosecutors lacked a clear suspect motive, and the new Freeform episode premieres Sept. 14.
